Rihanna, Coldplay Perform At Grammys: 'We Found Love,' 'Princess Of China' And 'Paradise'

Rihanna started with "We Found Love," during which she writhed around on the crowd until the Calvin Harris-produced track came in. The singer's blonde 'do gave the performance a twinge of Tina Turner.

Chris Martin and his guitar then joined RiRi for "Princess Of China," a much more stripped down performance. The full band then performed "Paradise."

It was a big night for electronic music. Chris Brown also performed a song that was produced by a house music artist ("Beautiful People," by Benny Benassi), Skrillex won three awards in the pre-show and deadmau5 and David Guetta were expected to perform later in the show.
